I just killed EVERY SINGLE FISH in my tank with FWE this week.... BE SUPER CAREFUL. In retrospect, I would have removed the fish prior to treatment.

I did everything according to the book with the treatment. I have used FWE in the past several times without much issue....the only thing I can think is there were a lot more worms than before this time around, even despite my siphoning what I could out prior to treatment.

Frankly I am having one of those "why am I doing this hobby moments" today...as I look at a line up of dead fish bodies sitting next to my tank. Not to mention a bunch of really ticked off corals.

Awwww Jim I'm soooooo sorry I totally understand your feelings right now Wish I could do something..... This news breaks my heart and puts fear in there too.....

The last time I used it, I double dosed with great results. Actually I wasn't even aware of how many worms I actually had in there until I treated and they began floating throughout the tank. Scared the crap outta me!!! I started netting within minutes and was doing a water change within 20 minutes. I'm going to try the same thing this time. I hate using chemicals of any kind..even 2 part but my tank is just to small for any of the natural predators available

Wow sorry to read that. The fw do create a toxin they release when they die. You must have allot of worms !! This is tthe first time of reading of a complete die off from this product. Guess if I use this again it will be fishing time befor treatment! Thanks for the heads up Jim
